Deprecated.

In favor of ProblemFactCollectionProperty.

public @interface ProblemFactCollectionProperty

Specifies that a property (or a field) on a PlanningSolution class is a Collection of problem facts. A problem fact must not change during solving (except through a ProblemFactChange event).

The constraints in a ConstraintProvider rely on problem facts for ConstraintFactory.from(Class). Alternatively, scoreDRL relies on problem facts too.

Do not annotate planning entities as problem facts: they are automatically available as facts for ConstraintFactory.from(Class) or DRL.
